BR-CO-19 — Invoicing period without a date (BG-14)

• Standard: EN16931
• Severity: fatal
• Business Terms: BT-73, BT-74

Meaning

If the INVOICING PERIOD group (BG-14) is used, the start date (BT-73) or the end date (BT-74) — or both — must be filled.

Possible causes

• cac:InvoicePeriod is present but neither cbc:StartDate nor cbc:EndDate is set.

How to fix it

• Set BT-73 (cbc:StartDate) and/or BT-74 (cbc:EndDate) inside cac:InvoicePeriod, or drop the empty group.

Affected fields

• /ubl:Invoice/cac:InvoicePeriod/cbc:StartDate
• /ubl:Invoice/cac:InvoicePeriod/cbc:EndDate
